[Case Study] Rehabilitation of Sewer Manholes

Introducing case studies aimed at the rehabilitation of manholes affected by hydrogen sulfide corrosion.

We would like to introduce a case where "D-Hole (Docking Hole)" was implemented for the rehabilitation of sewer manholes. In the Waterworks Division of the Yakage Town Hall in Okayama Prefecture, measures were being taken for areas where hydrogen sulfide corrosion was significantly advanced. This time, they adopted the D-Hole using the "Cassette Method," which is gaining attention for its new construction technique. [Evaluation] ■ Although it was their first time using this method, they confirmed a certain level of effectiveness in terms of construction method, duration, and cost, and expressed a positive intention to consider its adoption in the future. *For more details, please refer to the PDF document or feel free to contact us.
